You cannot CE mark a roof truss as it is part of a house. You must CE mark the entire house.

It's rarely worth it to make your own roof trusses.
It's cheaper than many people think to order ready-made ones.
Just a tip

Exactly.hantverkare1 said:
Small trusses for garden sheds and such can be profitable to nail together yourself, but at spans of 4-6 meters, all profit usually disappears, leaving only completely "unpaid" working hours, if it doesn't even become a pure loss.
However, maybe a bit OT.
Otherwise, I think it's like pelle242 writes.
Agree.
I built a 60 m2 workshop with a 45-degree roof angle a couple of years ago. The trusses cost about 15,000 SEK from the factory.
They were calculated, documented, made from graded timber, and delivered.
If you want to do something similar yourself, you need to build a jig and also have access to a crane and a helper. It's not something you handle manually, exactly.
Another aspect is safety, responsibility, and insurance. If something were to happen due to incorrectly calculated trusses, you would be in trouble as the responsible designer. Future building permits for modifications may also depend on having proper calculations and construction drawings.
In short, buy them pre-made.

The trusses for my garage weren't expensive by themselves, but with the shipping, the total amount was so large that it would have cost me 2-300 kr/hour if I had made them myself. For the residential house, the shipping made up a smaller part, the lumber a larger part, and it would have taken much longer to make them myself, so there was nothing to save there.
I have personally built all the trusses for 4 different constructions. These are smaller trusses now, 6.5 meters wide and 2.2 meters high was the size of the largest one. It's not much trouble to do it yourself. I had help from 2 retired construction managers, so it went quickly. The dimensions are easy to determine, request a quote and you get them for free. You also get a price estimate and can calculate if it's worth making them yourself. I made mine for about 1/3 of the cost of buying them ready-made. Now, this was 8 years ago, I might have bought them ready-made today as I don't have the same possibility for help.
Do you really get construction drawings from the truss manufacturer already at the quoting stage? I didn't get that when I built my house; the owner of the truss company dropped by, and I got to look at the drawings when we discussed different things, but I wasn't allowed to keep them. In my case, it ended with me ordering not only the advanced scissor trusses but also the much simpler "w-trusses" because the company both had a good price and was very pleasant to do business with.
You can talk about that for a long time. If they give me the information for free without me having asked for it, then it's kind of up to them. Now I can calculate this myself.injonil said:
